fix: Fix backups bug for Linode Interfaces

[coliu-akamai]

Description 📝

The Network Connection selection field is incorrectly disabled on the backups page. It should only be disabled if interface type is Configuration Profile Interfaces

Changes 🔄

• keep previous interface generation type when selecting a Linode on the backups page
  • (we don't want to use linode.interface_generation for here because the selected linode might have a different interface generation type than what's allowed by our account setting )
• Hide VLAN/VPC interface fields if unable to select Network Connection type + clear vpc/vlan fields in case they were already touched when selecting Config profile on backups tab to prevent hidden errors
• moved up logic to disable Interface Type, since I'm also using this to determine when to hide VLAN/VPC stuff

Scope 🚢

Upon production release, changes in this PR will be visible to:

• All customers (I think?)
• Some customers (e.g. in Beta or Limited Availability)
• No customers / Not applicable

How to test 🧪

Prerequisites

Have a Linode that has a backup

Reproduction steps

For all account setting options except for Configuration Profile Interface only:

• Navigate to the the Create Linode from Backups page. Before selecting a Linode, note the interface generation type is correct (linode)
• Select a Linode with a backup - notice how interface generation type becomes undefined
• Networking Connection type is disabled (even though selected interface type is Linode in the UI, underlying value is undefined)

For an account setting with Configuration Profile Interface only:

• Navigate to the the Create Linode from Backups page. Before selecting a Linode, note the interface generation type is correct (legacy_config)
• Select a Linode with a backup - notice how interface generation type becomes undefined
• Networking Connection type is disabled but
• Network Interface type is incorrectly set to Linode even though it should be Configuration Profiles - this is because if interface generation type is undefined, Linode is now always chosen

Verification steps

• Confirm when you select a Linode from the Backups table, the Interface Generation type is what you'd expect
  • Configuration Profile Interfaces for 'Configuration Profile Interface only' account setting
  • Linode Interfaces for all other Account setting options
• and that the Interface Type is only disabled when Interface Generation is 'Configuration Profile'
• Confirm that creating a Linode in the other flows (os, stackscript, etc) still works fine
• Confirm that cloning a Linode still works fine
